| Outline of Final Research Achievements |
A new class of ionic liquids based on phosphonate anions and carboxylate anions with functional groups have been synthesized and their properties investigated and applied to cellulose dissolution. In the present study, anions having polar groups, such as ether group and amino group, were found to display greater hydrogen bonding basicity than conventional polar ionic liquids. In particular, we have successfully developed a new class of polar ionic liquids that display strong hydrogen bonding characteristics and cellulose solubility in the presence of water. By designing cation structure to give rise to hydrophobicity, a new class of ionic liquids that are both hydrophobic and polar. These comprise ionic liquid/water biphasic systems showing strong hydrogen bonding characteristics in the presence of water. Moreover, by designing cation to control the affinity with water, polar ionic liquids showing lower critical solution temperature behavior with water have been developed.
